TRUSS-PAD.

SPECIFICATIN forming part of Letters Patent No. 453,298, dated J une 2, 1891. Application leci December 8, 1890. Serial No'. 373,915. (No model.)

.T0 el! wlw/1L t may concern:

lle it known that'I, Geenen R. Futuna, of Rochester, in theeounty of Monroe and State of New York, have invented a new and useful Improvement/'in '.l'russ-lads, which improvement is fully s et lorth in the following lspecification and shown in the accompanying drawings.

worn orused -morepar' rcularly to support the parts'in the case of lrupture or hernia; and the object ofthe in' ention is in part to hinge the pressing paiitr r pad proper at one side or edge, so that it, 1' .ay have a swinging motion to v'more nearly imitate a linger-pressu re against the disCrd-ered parts.

The object of, the invention is also to lurnish means lor conveniently adjusting` the pressing piece or pad proper, so Athat it may exert a greater or less pressure against the weakened o'r disordered parts.

'l`hein.'entien isherejnafterlullydescribed, and particularly pointed outin the claims.

referring lo the drawings, l-igure l is aview ofthc pad, showin;r the side or tacev turned next-the wearer; l ig. 2', a similar view with the pad prfnliertiu'ncd up and detached, a part ot the rubber ring being broken away; Fig. 15, a central longiti'idinal section of the device, taken on the dotted line .l i. in Vig. 2; and Fig. l, a View of :rplate cennnonly used with these pads,showine'the latter in various positions et' adjustment by dotted lines.

Referrinr to the parts, .f\ is the front plate or part for holdinlr the pad, which plate is usually made ol' hard rubber and may be in i forni, this particular partol the device not being a partfof my invention.

n is an oval flaring` cup-shape piece or cup secured to the plate hy a hollow sleeve-screw l), passed through an opening o in the plate and threaded ecntmlly inthe bottom ol' the eup.

l isa thick sott-rubber ring or cushion surrounding the cup and in contact with the plate, it bei'in.;` held under the inclined or Haring sides' el' the cup against the plate. '.lihe slecve-screw is formed with an external the outside o" the plate.

fl is a strip of metal acting.,r as a lever, held within the eup and secu red at one end to the bottoni thereof by a fasteningserew e.

v beneath the free end of the lever d.

ll .is a depressingpieee to bear against'the abdomen of the wearer and eonstitutes'the pad proper of the device. This piece or pad is hinged at one end on a pin Iz., also securedv in the sides ef the cup in a position parallel with the pin g and at tudinal line of the le'ver d. Thus hinged the pad is permitted to swing toward or from the month of the cup, like a cover therefor.' The pad ll is formed with a. rigid stud i in position to bear the leverf,` as shown in Fig.

right angles to alongiagainst the outer or free end of '.l`he piece d is held rigidly tothe bottoinof the cup at 011e end by stated, and acts as a spring-lever to bear against the inner end of thebent 1everf, tendl ing to keep said end ot the bent level' down against the bottom of the cup. This vlever d is rc-enforeed by a stiff spiral spring gheld to bear-against it by an adj Listing-screw land cap-nut n. 'l'he screw! passes longitudinally through and hasabcaringin the sleeve-screw Il, and is provided at its outer end with a milled head I', which is also creased at its outer flat face to receive asereW-driverin the usual manner.

You' it will be understood ver fconstitutes a spring-pressed lifter for the pad ll, and that any pressure against the outer convex surface of sisted by the spring and other words, lthe action of the screw e, as above the lever cZ, or, in the spring and the lever l upon the lever ften '.s to' throw theend ot' the 'p ad B forward' against the abdomen also, on aecountot' the pad being hinged tothe cup at one end itsA lower or free motion is a swinging` motion, causing it t0 press upward against theperejon, .as-Well as forward, .from the action of'thespringiasobove stated. ily turning.)r the adjusting-screw Z in a mannertodraw the nut/1t farther down against the spiral spring the vpad B will b'e caused tov press harder against, the wearer', while if the adjusting-screw he turned in the that the bent leopposite direct-ion the pressure of the pad will be reduced. By means ot this adjusting screw and spring any desired degree of pressure may be brought to bear upon the person of the wearer by the pad.

It .the plate is Jformed, as shown in Fig. t, with slots o to receive the fastening sleeve screw h for the pads, the latter may be adj usted in directions toward or from each other, while the pads may also be turned upon the plate as with a swivel movement, thus bringing them to any desired positions and to bear upon the affected parts as may be required in any given case.

It is plain to be seen that the piece d may be dispensed with by lengthening the inner arm of the loverf, so as to carry it under the spiral spring, having a hole formed in it to clear the screw Z. I` prefer, however, to einploy the piece d, as shown.

The cushion E extends high above the mouth of the cup, the latter serving, however, to keep it clear ot' the swinging pad B.

What t claim as my invention. is-

1. A truss-pad consisting of athick soft an nular ring of rubber, the bottom or Viflat portion. of which is ytflaptd'to rest upon t'he'front platte; a eup-shaped piece ttingwithiu the ring with its sides projecting over the lower artof the innerl portion of the ring and adapted to hold the same in contact with the plate, a yielding pad secured to the cupnhaped piece, and means for holding the bottom of the eup-shaped piece against the plate, substantially as described.

end within the same, the innerkside of the pad being provided with an i11nn'trdly-p'roject-5` ing lug or projection, a lever pivotally secured within the ring, one end of which bears against the lug upon the pad, and a spring for actuating the opposite end of the lever, substanf tially as described.

3. In a truss, the combination, with a trussplate, of a perforated front plate, a cup-shaped piece, the bottom of which is provided with a screw-threaded perforation, an annular ring outside of the cup-shaped piece', a springactuated pad within the ring, a ,hollow sleevcscrew through the plates and into the bottom of the cup-shaped piece, and an adjustingscrew through the hollow screw for regulating the spring-pressure of the pad, substantially as described.v

V4. An improved pad for a truss, consisting of a cup and a holding-plate therefor, in comf bination with a pressing piece or pad proper hinged to the cup, a bent lever pivoted within the cup, a lever d to press said bentlevelg'.

a spring bearing against said lever' cl, and an' i adjusting'scre'w and nut toA control thespririg, substantially :is shown and described.

In witness whereof I have hereunto set my hand, this 4th day ot December, 1890, in thc presence of two subscribing witnesses.
